How to calculate the area of a square

Answers

Answer:

a × a × a ×a

Step-by-step explanation:

Area is measured in "square" units. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.

Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

Answer:

  A  function 2

Step-by-step explanation:

"Rate of change" in this context refers to the slope of the line.

Function 1

The slope of the line is the "rise" divided by the "run". That is, the vertical change between two points divided by the horizontal change between two points. Usually, we like to choose points where the line crosses gridline intersections. One of these is the y-intercept (0, -2). Another is 2 units right and 1 unit up at (2, -1).

The slope of function 1 is then ...

  m = rise/run = 1/2

__

Function 2

The equation for function 2 is written in the "slope-intercept form." That is, the form is ...

  y = mx + b . . . . . . . . where m is the slope and b is the y-intercept

Comparing this form to the given equation, we find ...

  m = 5/2, b = -2

The slope is m = 5/2.

__

The slope of function 2 is 5/2. That is greater than the slope of function 1, which is 1/2.

Function 2 has the greater rate of change.

Step-by-step explanation:

45*2=90

Remmy typed 84 words in 2 minute:

work

420/10=42 words a minute

42*2=84

Izzy typed 98 words in 2 minutes:

work

588/12= 49 words a minute

49*2 = 98

I hope this helps :)

Answer:

C

Step-by-step explanation:

We need to find how many words each of them can type in 2 minutes.

Justin-

Justin can type 135 words in 3 minutes. First, find how many words he can type in 1 minute:

135/3 = 45 words per minute

Then, multiply by 2 to find how many words he can type in 2 minutes:

45 * 2 = 90

90 < 95, so he is eliminated.

Remmy-

Do the same as we did for Justin. Find the number of words she can type in 1 minute:

168/4 = 42

Multiply by 2:

42 * 2 = 84 words per minute

84 < 95, so she is eliminated.

Izzy-

Find the number of words she can type in 1 minute:

147/3 = 49 words per minute

Multiply by 2:

49 * 2 = 98

98 > 95, so she can type a minimum of 95 words every 2 minutes.

Sarah needs 3 feet of fabric for a project she is working on, but the store only sells the fabric in meters. One meter of fabric costs $1.20. How much will the fabric cost? [1 ft = 0.305 m]

Answers

Answer:

The 3 feet fabric will cost $ 1.09728 almost $ 1.10

Step-by-step explanation:

First we will find out how many meters 3 feet will be.

1 feet = 0.3048 meters

She needs 3 feet of fabric

3 *1 feet = 3* 0.3048  ( multiplying both sides by 3)

3 feet = 0.9144 meters

Using the unitary method we will find the cost of 3 feet of fabric

1 meter costs $ 1.20

0.9144 *1 meter costs $ 1.20 * 0.9144  ( multiplying both sides by 0.9144)

0.9144  meter = $ 1.09728

The 3 feet fabric will cost $ 1.09728 almost $ 1.10

Answer: 1.10

Answers

Answer:

24

Step-by-step explanation:

Line segment ON is perpendicular to line segment ML. Line segment OM = 13 units in length, line segment PN = 8 units in length.

Circle O is shown. Line segments M O, N O, and L O are radii. Lines are drawn to connects points M and N and points N and L to form chords. A line is drawn from point M to point L and intersects line O N at point P. The length of O M is 13 and the length of P N is 8. Angle O P L is a right angle.

The Length of the Chord ML is; 24 Units

What is the Length of the Chord?

From the question, we are told that;

MO, NO and LO are radii.

Now, If MO = 13,then LO = NO = 13

However, if NO = 13 and NP = 8, It means that;

PO = NO - NP

PO = 13 - 8 = 5

With the aid of Pythagoras Theorem, we can find MP:

MP = √(MO² - PO²)

MP = √(13² - 5²)

MP = √(169 - 25)

MP = √(144)

MP = 12 units

Now, P is the midpoint of Segment ML, Thus;

MP = PL

ML = MP + PL

ML = 12 + 12

ML = 24 units

Determine the perimeter of the composite figure. Implement the above in c++, you will write a test program named create_and_test_hash.cc . Your programs should run from the terminal like so:./create_and_test_hash should be "quadratic" for quadratic probing, "linear" for linear probing, and "double" for double hashing. For example, you can write on the terminal:./create_and_test_hash words.txt query_words.txt quadratic You can use the provided makefile in order to compile and test your code. Resources have been posted on how to use makefiles. For double hashing, the format will be slightly different, namely as follows:./create_and_test_hash words.txt query_words.txt double The R value should be used in your implementation of the double hashing technique discussed in class and described in the textbook: hash2 (x) = R (x mod R). Q1. Part 1 (15 points) Modify the code provided, for quadratic and linear probing and test create_and_test_hash. Do NOT write any functionality inside the main() function within create_and_test_hash.cc. Write all functionality inside the testWrapperFunction() within that file. We will be using our own main, directly calling testWrapperFunction().This wrapper function is passed all the command line arguments as you would normally have in a main. You will print the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 2 (20 points) Write code to implement double_hashing.h, and test using create_and_test_hash. This will be a variation on quadratic probing. The difference will lie in the function FindPos(), that has to now provide probes using a different strategy. As the second hash function, use the one discussed in class and found in the textbook hash2 (x) = R (x mod R). We will test your code with our own R values. Further, please specify which R values you used for testing your program inside your README. Remember to NOT have any functionality inside the main() of create_and_test_hash.ccYou will print the current R value, the values mentioned in part A above, followed by queried words, whether they are found, and how many probes it took to determine so. Exact deliverables and output format are described at the end of the file. Q1. Part 3 (35 points) Now you are ready to implement a spell checker by using a linear or quadratic or double hashing algorithm. Given a document, your program should output all of the correctly spelled words, labeled as such, and all of the misspelled words. For each misspelled word you should provide a list of candidate corrections from the dictionary, that can be formed by applying one of the following rules to the misspelled word: a) Adding one character in any possible position b) Removing one character from the word c) Swapping adjacent characters in the word Your program should run as follows: ./spell_check You will be provided with a small document named document1_short.txt, document_1.txt, and a dictionary file with approximately 100k words named wordsEN.txt. As an example, your spell checker should correct the following mistakes. comlete -> complete (case a) deciasion -> decision (case b) lwa -> law (case c)Correct any word that does not exist in the dictionary file provided, (even if it is correct in the English language). Some hints: 1. Note that the dictionary we provide is a subset of the actual English dictionary, as long as your spell check is logical you will get the grade. For instance, the letter "i" is not in the dictionary and the correction could be "in", "if" or even "hi". This is an acceptable output. 2. Also, if "Editors" is corrected to "editors" that is ok. (case B, remove character) 3. We suggest all punctuation at the beginning and end be removed and for all words convert the letters to lower case (for e.g. Hello! is replaced with hello, before the spell checking itself).Do NOT write any functionality inside the main() function within spell_check.cc. Write all functionality inside the testSpellingWrapper() within that file. We will be using our own main, directly calling testSpellingWrapper().
